The first step in selecting the proper 3M™ Dyneon™ Fluoroelastomer for your application is to consider the service environment – the chemicals and temperatures your part will encounter. The charts below illustrate the broad chemical and temperature resistance of 3M fluoroelastomers. Use these charts to help guide your search for the 3M fluoroelastomers that can deliver the desired performance for the environment.

If you do not find your chemical class here, please contact us at the location on the back of this brochure or visit our web site, 3M.com/fluoropolymers, for more information.

u Did you know? FKM (by ASTM D1418 standard) (equivalent to FPM by ISO/DIN 1629 standard) is the designation for about 80% of fluoroelastomers as defined in ASTM D1418. Other fluorinated elastomers are perfluoroelastomers (FFKM) and tetrafluoro ethylene/propylene rubbers (FEPM). All FKMs contain vinylidene fluoride as a monomer.

The most important determinant of thermal stability is the curative package used. As indicated in the chart below, fluoroelastomer compounds based on bisphenolic cure systems show a slightly more beneficial thermal stability than compounds based on peroxide cure systems. The best performance can be attained with perfluoroelastomer grades which are specially designed for high temperature applications. These grades take advantage of a triazine cure technology.

Permeation Data for Elastomers Commonly Used in Automotive Applications

Fuel SystemsRegulations around the world continue to adopt more stringent fuel emission standards. 3M fluoroelastomers are commonly used in fuel system applications because of their excellent permeation resistance, effectiveness as barriers against evaporative emissions, chemical resistance to a broad variety of fuels and long-term durability.

Fuel ApplicationsFuel line hose, filler neck hose, chemical transport hose, in-tank hose, injector o-rings, gas caps, sender seals

What's important for optimum performance?• Chemical resistance to a wide range of fuels

• Volume swell and property changes over time

• Sealability

• Permeation resistance (see chart below)

• Performance over temperature range

Permeation TestingNew global regulations have tightened the restrictions on the allowed amount of evaporative emissions from automobiles. These regulations make it increasingly important to understand and develop permeation measurement techniques that allow for accurate characterization of a polymer or part. 3M is recognized in the automotive industry for its expertise and developments in permeation test methodologies that yield results that are accurate, reproducible and can be scaled to commercial constructions. For more information, see SAE Technical Papers 2000-01-1096 and 2001-01-1126 (www.sae.org).

What’s the manufacturing process?Step 3

u Did you know?

• Post cure is critical for optimum performance and optimum compression set.

• Fluoroelastomers can be calendered to <0.25 mm thickness.

• Fluoroelastomers offer excellent resistance to weathering, including UV resistance.

Processing ConsiderationsThe type of manufacturing process you plan to use to produce your part will have an impact on the fluoroelastomer you choose.

3M™ Dyneon™ Bisphenol-cured Fluoroelastomers are considered by many to be the best-processing fluoroelastomers on the market today. We offer a large selection of incorporated cure gums to help you develop the most robust compound for your process.

What’s important for optimum performance?• Mooney viscosity • Flow rates • Scorch safety

• Cure speed • Demoldability

Manufacturing Processes Injection MoldingChoose a low to medium viscosity (20 to 60 MV) gum with excellent scorch safety and a fast cure.

Transfer MoldingChoose a low to medium viscosity (20 to 60 MV) gum with good scorch safety to avoid curing in the transfer pot.

Compression Molding Choose a medium to high viscosity (50 to 90 MV) gum with a fast cure cycle.

ExtrusionChoose a low viscosity (20 to 40 MV) gum with good scorch safety. Many times process aids can be used to improve flow and surface smoothness, but are not always necessary.

CoatingSolution viscosity is determined by the solvent used and filler level. Solution stability (pot life) is of key concern.

Post CuringTo achieve the optimum physical properties, post curing fluoroelastomer parts is recommended.

For bisphenol cured compounds, optimum properties can be achieved with a post cure of 4 to 16 hours at 230°C to 250°C depending on size of part and efficiency of the oven.

For peroxide cured compounds, optimum properties can be achieved with less aggressive post cure conditions of 2 to 8 hours at 200°C.

If optimum physical properties are not required for a specific application, a post cure step may not be required.

u Did you know?

• For hose applications, consider using 3M™ Dyneon™ FE 5830Q. This product offers excellent processing as well as low permeation and volume swell.

Key Considerations for O-rings

Key Considerations for Extruded Shapes

The most important consideration for an o-ring application is usually the compression set. As a general rule, the higher the viscosity of the fluoroelastomer, the lower the compression set.

Viscosity can be an important consideration when choosing 3M Fluoroelastomer grades that will be injection molded.

3M™ Dyneon™ FE 5620Q and 3M™ Dyneon™ FE 5621 are suitable for injection molding and offer excellent compression set resistance.

Other considerations for o-rings include:

The following chart shows the available 3M fluoroelastomer products with their respective fluorine contents and applicability to various processing techniques.

Fluoroelastomer hose is used in a variety of applications – from automotive fuel line and turbocharger hose to extruded o-ring cord.

What’s important for optimum performance?• Flexibility

• Chemical resistance, in particular permeation resistance

• Fluid pressure

• Material and surface hardness

• Sealability at the hose ends

• Performance over service temperature range

• Extrudate surface requirements

Post Curing To achieve the optimum physical properties, post curing fluoroelastomer parts is recommended. For peroxide cured compounds, optimum properties can be achieved with less aggressive post cure conditions of 2 to 8 hours at 200°C. If optimum physical properties are not required for a specific application, a post cure step may not be required.
